provide a car doorconstruction comprising a. main body portion-in the form of a metallic sheet-or sheets, with'means for providing a tubularformation along the edge, or edges, of the door, said ineansincluding stiffening elements, which may be of commercial form, secured adjacent an edge of the door sheet and extending at' an. angle thereto, in conjunction withother reinforcing elements secured to theouter extremities of the stiffening elements, and extendinginwardly toward the door sheet and secured thereto in spaced relation with reference to the first mentioned stiffening elements. v

A more specific'object of the invention is to provide a tubular edge formation for a,

door body sheet in which the door sheet may be utilized as one wall of the tubular formation without the necessityfor bending or otherwiseishaping or forming the same, the remaining walls of the tubular formation being provided by the stiffening ele ments which are arranged and secured to --the door sheet in a simple and effective manner.

Otherobjects and advantages of the invention will more clearly appear from the description and claims hereinafter following.

Figure 7 is an enlarged, broken, horizontal, sectional view corresponding to the section line, 7-7 of Figure 6. Figure 8 is an enlarged, broken, vertical, sectional view corresponding to section line 8-8 of Figure 6., Figure 9 is an enlarged, vertical, sectional view similar tov Figure 8 showing the door when utilized in connection with the, so-called top hung type of mounting; and Figure 10 is an enlarged, broken, horizontal, sectional View, of another slightly different embodiment of the invention, such figure being of the same character as that illustrated in Figure 7.

Referring first to the construction illustrated in Figures 1 to 4 inclusive, 10'-in dicates the usual side wall of a boxcar, 11 the floor boards, 12 the car side sill, 1 3 the door postsor jambs at the front and rear the lintel of the door frame.

' In the arrangement illustrated in Figures 1 to 4 inclusive, a sliding outside door is shown designated generally by the reference character A. The door A comprises a main body portion, of a size and sha e as to cover the door opening, and such ody portion and 14 indicates may consist of a single flat metallic panel or-sheet, or a plurality of metallic panels or sheets as indicated in dotted lines, in the drawings, secured together by any suitable means to provide a rectangular formation, and such main body panel= or sheet also may be provided with suitable strengthening elements inwardly of the edges thereof, if deemed desirable to thus strengthen the sheet in that portion within the reinforced edge construction as contemplated by my I m5 invention.

Secured to the top, bottom and forward marginal edges of the main body portion 15, of the door are reinforcing or stiffening ele ments' in the form of Z-bars 19. Each of the Z-bars has one flange-20 secured to the main body portion of the door by means of countersunk rivets 21, all the flanges 20 being ardoor, and formed with the outer end of the .web is an inwardly turned flange 23 extending in substantial parallelism with the .body portion'of the door. The Z -bars 19 are beveledat the corners of the door, as

"indicated at 24, and secured together in any suitable manner.

The rearmarginal edge of the door panel is provided with an inturned flange 26 to which is secured an angular member 27, by means of rivets 28 whichv are countersunk on the inner side of the flange 26, the' intermediate portion 29 extending outwardly.

from the door plate 15 in a perpendicular direction, and being provided withan inturned flange 30 which is disposed in the same plane as the flanges 23 of the Z-bars. The angular member 27 is provided on the inner side of the flange 26 with an inturned flange 31 which in conjunction with the angular member 32 secured to the door post 13-, functions as a spark or weather strip when the door is in operative position.

Secured to the outer flanges 23 of the Z bars 19, and to the flange 30 of the angular member 27, by means of-rivets 33, are the turned end portions 34 of bracing strips 35,

each of said bracing strips being of suitable metallic construction and including an in clined web 36 which extends in an inward direction between the flanges 23 of the Z-bars and'the flange 30 of the angle member 27,

towards the door sheet 15, such reinforcing strips being provided with flanges 37 which are secured to the body portion of the door by'means of rivets 38, the bracing strips 85' being identical in form, and having their ends beveled as indicated at 39' to provide a neat and efficient construction.

. By the above described arrangement a. plane metal sheet or panel or plurality of panels isprovided with a tubular edge con struction of great strength and rigidity, "nee cessitating the use of a minimum of material, and providing a doorwhich may be asso ciated with mountings of an ordinary character, as will now be described.

The door may be utilized as the so-called top hungtype, or as the so-called bottom hung type. In mounting the door as a bottom hung door, the usual track 39 may be provided which is secured to brackets 40 fastened to the side sill 12. .VVith this construction rollers are usually mounted on the door proper, and in this connection a door constructed in accordance with the principles heretofore explained, lends itself to the application of rollers which operate upon the track 39. Disposedwithin the tubular edge formed by the bottom Z-bar 19 and 4 .Loae'httod strip 35, and the adjacent portion of the door sheet at the bottom of the doorare supporting brackets 41. Each of said brackets, carries a pin 42, upon which a roller 43 is mounted, such roller extending outwardly through a slot 44: in the web of vthe Z-bar 19 so as to .bear upon'the track '39, or if desired the tubular formation may be cut out at th' point of application of the brackets 41, it being noted in either event that the flange 20 of the Z-bar and the adjacent marginal side of the door portion project behind the adjacent portion of the bracket 40 and the track 39 so as to limit the outward movement of the door when the same is operated. The top edge of the door 15 is formed by the flange 20 of the Z-bar 19, and the adjacent marginal edge of the portion 15, such edge projecting behind the flange portion 45 of the angular member 46 secured to the door frame by suitable rivets, thereby limiting the outward movement of the door, but permitting-sliding movement thereof. The angle member 46 may be secured to the top of the door so as to be disposed outside of the flange 455 on the member. 46 to provide means for limiting inward movement of the door. The forward edge of the door due to the disposition of theZ-bar provides a projecting flange portion adapted to be received between the door wear plate 17,

and the cover strip 48. The angular member.

27 at the rear edge of the door is provided with the inturned flange 31 providing a spark strip which cooperates withtlie angular member 32 secured to the adjacent door post 13.

If the door mounting is ofa type wherein the rollers are carried by brackets secured to the car structure, it will be obvious that the disposition of. the Z-bar, and related members at the bottom edge of the door, permit the door to be used efliciently in connection with this type'of mounting As shown in F igure l the bracket 50 as shown is connected to the side sill- '12, and each bracket 50 carries a roller 51. In this construction the door A is placed in position in the manner above described, the flange 20 of the Z-bar, and the adjacent bottom margin of the door extending behind the lit bracket 50, while the weight of the door is .slidably supported upon the web 22 of the Z-bar, such Z-bar of course being braced by the reinforcing strip 35.

- A slightly modified form of the invention is shown in Figure 5 of the drawing, this construction being identically similar with respect to that heretofore described, except for the arrangement of the rear edge portions of the door; all of such members therefore will be designated by the same reference characters heretofore used as designating similar parts. In the construction shown In Figure 5 instead of the angle memii ber 27 heretofore described, "a l-bar 60-isi aeaasee utilized,'one flange 61 of which is secured to .the rear edge of the door" plate, the web of such Z-barbeing disposed inwardly of .the edge of the door portion 15, and extend? ing perpendicularly outwardly from the door plate, and being provided with a flange 62 extending in substantial parallelism with the body portion of the door and to which the flange 34 of thebracing strip is secured. A spark strip 63 is secured to the rear edge of the door, such spark strip including a flange which extends parallel with the flange 61 of the Z-bar, and including a flange 64 having an inwardly turned portion (35 adaptedto co-operate with a suitable angle member 1 66 secured to the adjacent door post 13.

' Referring to Figures 6 to 9 inclusive, another slightly different embodiment of the invention is illustrated. In this construction the main door sheet 100 may be of metal, and formed as a'single sheet or. panel, or made up of a plurality of sheets or panels suitably secured together, and such panel may be provided with a plurality of strengthening corrugations if desired. Secured to all four marginal edges of the panel 100 are Z-bars 101, each of such Z-bars including a flange 102 secured along the mar-.

ginal edge of the door sheet 100, a web 103 extending perpendicularly to the main body sheet, and an outwardly turned flange 104 extending in substantial parallelism with the main body'sheet 100, such flanges being secured to the body sheet by rivets 105, sa-id' 'Z-bars being beveled at 106 and secured together by any suitable means. Aflixed to the inner faces of the flanges 104 of each of the Z-bars, is a reinforcing strip 107. Each of such strips comprises the flange-portion 108 secured to the flange 104 of each Z-bar by suitable rivets which may be counter? sunk on their opposite sides,- the flange 108 extending inwardly beyond the Z-bar a suitable distance and being provided with a web 109 preferably extending perpendicularly with reference to the main body sheet 100. the portions of the web 10.9 adjacent.

the body sheet being provided with a flange 110 which is secured to the body sheet by rivets 111. The rear edge of the door is provided with an angular member 112 having :1 turned portion 113 providing a spark strip adapted to co-operate with the angular member 114 secured to the door post 115. At the bottom of the door, as well as along its side and top edges, the Z-bars' 101 and re-inforcing strips 108 provide a tubular member in which may be mounted the rollers 116, suitable brackets 117 being provided which fit within the tubular member and are secured therein, the rollers extending-outwardly through the slots 118 in the web 101 of the Z-bar so as to restuponthe track 119 the brackets 120 at the bottom of, the door,

and behind the angular members 121 at the top of the door, the door being further proyided 'atthe top with anangular member flange 108 of the reinforcing strips are ar ranged toextend between the wear plate 123 on the door member 115, and an angular cover strip secured to such door post. By this arrangement a door is provided which has great strength andnecessitates the use of a minimum number of parts,'the tubular edges of-the door resulting in a great increase in strength. j

In Figure 9 there is illustrated the door structure used as a top hung door.- In this arrangement brackets 123 are secured to the top edge .of the door, such brackets having rollers 124 mounted therein arranged to travel uponthe track 125 secured to the door frame, it being noted that the flanges 104 of the adjacent Z bar, and the flange 108 of the re-inforcing strip project behind the downturned end 126 of the. track member, so as to limit the outward movement. of the door and retain the same in operative position.

In Figure 10 there is illustrated another slightly diiferent embodiment of the inven- 122 'whichlim'its inward movement of the door. The forward edge of the door provided by the flange 104, and the adjacent tion,.the door sheet 200 being-provided with 4 Z-bars 201 along the top, bottom and front edges-{such Z-bars and body member being connected by reitnforcing strips 202. which include flanges 203 secured to the body portion 200 of the door by rivets 204, the web of the reinforcing-strips 202-being inclined as shown. Each strip 202 is'provided with tio n of the member 206 being inwardly turned as indicated at 207 to provide a spark strip adapted to coperate with the angular member 209 secured to the door post'209. A reinforcing strip 210 has one end portion 211 connected to the angular member 206 by means of rivets 212, such reinforcing strip being inclined outwardly and provided with a flange 213 secured to the door sheet 200 by means of rivets 214.

In the arrangements herein described an important ,purpose of my invention resides in providing the tubular formation along the edges of the door, in such manner-that there is no necessity'for bending or otherwise shaping or forming the mainbody sheet of the door, the stiffening elements being so arranged that the main body portion offiche' sheet is utilized as part of the tubular-formation, the tubular formation bracing the edges of the door in VlI'lOLlS directions, and also providing a reinforced what I now consider the preferred mannerof-carrying out my invention, the same 1s merely illustrative and I contemplate all changesand modifications that come within the scope of the claims appended hereto.
